Figure 33. Examples of local neurons, SEZONs, and LHONs that target PAM11 DANs.
(A) All PAM11 DAN subtypes are shown, color-coded as in Figure 28 and Figure 28—figure supplement 1; the MB lobes are shown in gray and the α1 compartment is shaded brown. (B–F) Examples of neurons from clusters in Figure 30 that provide strong input to PAM11 DANs or to PAM11 and other positive-valence PAM DANs are shown; cluster identity is indicated by the circled number in the upper right of each panel. Neuropils where DAN input clusters receive their inputs are shown in gray (except for SEZONs whose dendrites are not in the hemibrain volume) and position of output synapses to PAM11 subtypes are shown color-coded; synapse numbers are given in parentheses. Figure 33—figure supplement 1 shows more information about the neurons constituting these clusters. (B) The single neuron in cluster 22, a SEZON, makes synapses to all three subtypes of PAM11 DANs; PAM11 DANs are the only DAN targets of cluster 22. The same applies to its contralateral partner (see Figure 35—figure supplement 1A). (C) The local interneurons that make up cluster 21 receive inputs in the SLP and connect to all three PAM11 subtypes, but not to other DANs. (D) The local interneurons that make up cluster 18 (299626157, 361700223) receive inputs in the SMP and connect to PAM11 DANs, but not to other DANs. (E) LHON cluster 20 connects to all three PAM11 subtypes and weakly to PAM01 and other positive-valence PAM DANs. (F) The LHONs cluster 19 connect to all three PAM11 subtypes and also to PAM13 (β′1ap), PAM14 (β′1m) and PAM01-fb (γ5) DANs (compare to Frechter et al., 2019, Dolan et al., 2019 , and Otto et al., 2020). The connections to the PAM11 and the other PAM DANs are located on different primary branches of the cluster 19 neurons. Connections contributing less than 0.5% of a neuron’s total dendritic input have been excluded.
